EUGENE TAYEaoE HYDE PAEK. MASSACHUSETTS-- To all 4whom it may concern Y Be it known that I, EUGENE H. TAYLOR,

a citizen of the United States, residing at Hyde Park, countyy of Norfolk, State `of Massachusetts, have invented a certain new.

anduseful Improvement in Insole-Forming Machines, of which the following is a specification, referencevbeing had therein to theaccompanying drawings.` V

My linvention relates to a novel machine for formingan insole ofthe general type shownl in U; S. Letters Patent No. 1,062,536

dated' May 20,1913 although it is not of the type claimed therein, said insole to be used" 1; in the manufacture of welt boots and shoes.

Heretofore in the manufacture of weltV boots and shoes it hasb'een common to prepare the insole for attaching the upper and welt by making an incision abouta portion of the edge of the insole and thereby forming a channel flap which is turnedup and secured to the upper and welt by stitching. The channel flap thus formed, however, is nec essarily thinner than the insole and therefore, in order that the channel flap shall have sufficient strength it is essential that' a relatively thick andv expensive piece of leather be employed `for the insole. The in sole shown in the saidLetters Patent has the Vadvantage of having'an integral chan` nel iapf or lip of as thick material as'that` of which the rest of the insole consists, but, so far as known to me, there has been no machine produced which will practically and commercially produce insoles in general like those shown and described therein.

My invention has, therefore, for its object to produce a machine which will make the said insoles rapidly and well.

My invention will be fully understood from the following description taken in connection with the accompanying drawings and the novel features will be pointed out and clearly defined in the claims at the close of the specification.

Fig. 7 is a sectional view of a machine embodying my invention equipped with a shaping-die" adapted vto form the inner insole member. 1a n e v l l y Fig. 8 1s a view 1n perspective of the'inner lblank after having been shaped in themachine shown in Fig. 7. Figs. 9 and 10 `are sectionsshowing successive positions of the operating members during the shaping of the outer insole member. Fig. 11 uillustrates the use of thefmachine for the purpose of assemblingthe insole members.

`I-Iaving reference to the drawings and particularly to Figs. l, 2, and 3, there is shown at A a fiat tablevor bed plate providedwith legs or supportingA members B and carrying a suitable die-supporting frame'or yoke C. j, The table A is provided, substantiallycentrally thereof, witha longitudinal opening 11 having at the sides oppositelydisposed guideways 12 andp13, and at one end a guideway 14. The frame C is rigidly secured to the table and supports 4a forming die 15 carried on the lower end of a slide rod 16 slidably mounted in the guides 17 which are preferably integral with the frame C. n p n .p

The shaping-die consists of a flat plate 19 which is of the proper size and shape for the particular insole to be formed and has about its lower edge a horizontal-lip or. flange 20 as is shown in Figs. 1 and 3. The liangeV or lip 20 may be made integral with the plate 19 or it may be formed by a `thin plate secured tothe bottom of plate 19. The plate 19, which is preferably relatively thick, is supported by a suitable head 21 to which it is detachably secured by bolts22. Integral 'with the head21, is a Vcollar 10( adapted to receivethe end of the slide rod 16, being secured to it by as'et-screw 18, sothat the shaping-die may be quickly changed from time to 'time as required for diiierent sizes and styles of shoes;

The shaping-die is so located that it is directly above the opening 11. AThe slide rod 16, which supports it is given areciprocating movement by means of a toggle joint consisting of an elbow lever pivoted at 24 to the frame C, one arm 23 of the el'- bow lever .forming the handle and the other arm 25 being connected to the link 26 at 27. The other lend of the link 26 is pivotally secured to the collar 29 fast on' 'the Patented Augxl, Y1915.` Application med Api11,1914. serialuaszarse.

Slide r'a '1c 'as' Shown jin Figa. .Thi-,downward movement of the rod 16 is limited by a suitable collar-730 which' strikes-against the lower guide member 17 adjustably secured to the slide rod by a screw 31; .By

thisarrangement the length of -the downlward'stroke`nia.y^be'adjusted as desired for reasonshereinafter to be set forth;A 1

In conjunction with the lshaping-die 15, It employnr 'yieldinglyfmounted work-support.,32;which is carried by a" slide rod v33 'I mountedy Ain fthe; guides 34 integralV with the y .supporting meinberD, -and secured to the bo'ttornf'oftherl table A asj shown. in Fig..2.`

Thework-support 32' comprises a .horizontal imfemb'ejr orl plateahavingxa flat upperv surface, parallel ;withfthe lower surfacek of the shaping-die, and a collar 35 to receive the. upper end of the slide rod B3. The

work-support is secured to the'slide rod 33.`

by a set screw 36 and may be removed from `the Ymachine when required. A helical )spring 37 surroundsthe slide rod 33, and is vthe upper guide 34 against which the collar 38 strikes.l The work-support is located directly below the shaping-die 15L and -is approximately of the same size'and shape as its lower surface. Whenthework-support is in Y fthe position normally given-it by the spring i conjunction "with what maybe termed eX-'V 37, itisslightly` above the table-as shownin Fig.12., Y

g TheV shaping-die Aand lwork-support act in v ternal forms which are slidably mounted on i the upper surface ofthe table A' ina manner clearly shown in Figs. 1 and 3. The external forms comprise side forms or presser members' 39 and 40 andan end form 48.

` Y The side-'forms are supported on plates 41 to ywhichthej7` are secured by set screws 42.

rIhe'plates 41 are each inturn secured to T-r'nembersj43 located 'in the slots or guideways12 and 13, .the T-e'Xtensi'on 45 of which extends through and snugly fits within the Y slots.v In orderthat thel plates may be adjusted-relativelyto the shaping-diey I pro-y vide slot and pin vconnections 46 with the T- members 43 allfjas clearly appears in Figs. 1

andl 3. The T-extensions 45 of the Tmem-r Vbers 43 extend downwardly to the `lower surface of the table A andin; order to prevent the T-members from having a tendency Y to move upwardly I provide each with a flat plate 47 which eXtendsoutwardly at each side beyond the -T-eXtensions and lies contiguous with the lower lower surface of the table. v*The side form 39 consists preferably ofa relatively thick flat plate, the compressing orV operating surface Aoflwhich lies adjacent the edgeof the bottomrplate 19 of the .shaping-die' andI has a Contour. 011 .outline whichexactly corresponds with that of the shaping-die plate. In the same manner, the

side form'40 has an operating surface which corresponds with the opposite side of the plate 19 so that when the forms are placed along the sides of said shaping-die plate they make a substantial fit therewith.

The toe form 48referred to above is secured to a plate 49 which is in turn adjustably secured to a T-member 501 supported on the tablcA inthe same manner as the other T- members described above. The toe form 48 also consists yof a relatively thick flat plate having-a.n;ope1atinfr surface adapted to cooperate with that of the eXtreme toe portion ofthe plate19. "As is shown' in Figs. 1 and 3, the operating ysurface of lthe toe form comprises two substantially straight surfaces 50 and llconnected by a curved surface 52. The side forms 39 and 40 have extensions 53 and 54 respectively which eX- tend almost 'to the toe of the shaping-die, and theL forms are so arranged that when they are, pressed together, in a manner hereinafter fto be described, the toe form cooperates with the side forms and the entire toe portion of the; shaping-die plate.19 is contiguous with the operating surface of the forms with the exception of the surface 52 which is preferably spaced slightly from the toe of the shaping-die plate 19 as shown in Fig. 3 for reasons hereinafter to be set forth. v

The arrangement for mounting the forms hereinabove described is important for the forms are thereby rendered interchangeable and the operator may make both rights and lefts on Athe same machine and with the same forms by interchanging the forms. This may be done by securing the side forms 39and 40 to the other side of the plates 41 and securing each of the plates 41 to the opposite side from thaton which it was before. The toe form 48 is then turned over. It will thus be seen that the machine is adapted to shape and form insoles for both left and right shoes by the salne forms.

The externa-l forms are movable toward and away from the shaping-die 15 in the slots 12, .13 and 14 in which the T-members are mounted,l and uniform and simultaneous movement is imparted to them by a toggle joint construction which may be operated by hand lever 55 or by other suitable mechanism. The hand lever 55 is pivoted at 5G to thelower side of the table A as shown in Figs. 1, 2, and 3 and is provided with a short elbow extension 57. A link 58 is pivoted as shown at 59 so that movement is imparted to it by the lever 55. The free end of therlink 58 is pivotally secured to a member 60. having a fulcrumA at 61 and connected in turn with the plate 47 by means of a link 62 pivoted at 63 and 64. The hand lever 55 is also lconnected with the form 39 by means of a link 65 pivoted at 66 to the lever and at 67 to a member 68 having afulcrum at 69 secured to the tablevand connected with the form 39 through a link 70 and suitable pivots 71 and 72. It will be readily seen from the above that the movement of the lever 55 from the position shown in Fig. 1 to that shown-in Fig. 3 will cause the forms 39 and 40 to be moved inwardly with a uniform movement and be brought forcibly to bear against the sides of the shaping-die plate 19. The toe form 48 is also moved inwardly by the movement of the said lever by the short link 73 pivoted at one end to the lever 55 as shown in Figs. 1 and 3 and at the other end to thelower side of the plate 47 with which said form is connected. By this construction therefore I am enabled to control the movement of all the forms by a suitable lever, and to cause them to press uniformly against the shapingdie. The movement or travel of the various members being simultaneous, the entire periphery of the insole is shortened at once and there is no space left between adjacent forms so that an evenly formed lip is produced on the insole. The collar 30 on the slide rod 1 6 is so adjusted that when it contacts with lthe lower' guide 17 the shaping-die will be substantially in the position shown in Fig. 4,

the bottom surface ofthe flange 2'0 on the y shaping-die being below the external forms an amount dependent upon the thickness of material to be shaped.

At 74' and 75 are shown guides secured to the table A in proper relation with `the work-s`upport so that the blank to be shaped, this being of the form shown in Fig. 5, may be accuratelyY placed on the work-support by the operator. The guides 74 are each secured to a member76 by the slotand pin connections 77 and the members V7 6 areV in turn secured to the table by the slot and pin connection 78 all as clearly shown-in Figs. 1.

and 3. The guides 75 are also supported on the table A in the position shown in Figs. 1 and 3 and are secured thereto by the slot pin connection 79. `These members may be made in any convenient form but are conveniently made of "thin strips of metal of the form and shape shown in Fig. 2 having depending front end S0 adapted to contact with the edge of the material of which the blank consists. They extendy inwardly toward the work-support and may be adj usted through the slot and pin connections described to have the proper' relative pos1- tion with the Vworksupport for blanks of any size to be operated upon.

The blank is cut substantially in the shape shown in Fig. 5, the toe portion being somewhat larger than the 'toe portion of the lower' surface 20 of the shaping-die plate 19. The guides 74fand 75 are so adjusted that whenthe toe portion 791 of theblank con- Y tacts with'the guides 75 and the edges 81 contact with the guides 74, the edge of the toe portion will protrude beyond the bottom surface of the shaping-die plate 19, and the edge of the work-support 32. The shaping-die 19 is then moved downwardly into contact with the blank holding it firmly in position on thework-support. TheeX- ternal forms 39, and 4S arein the position shown in Fig. 1 and should be adjusted so thatthere is a small space between them and the shaping-die as shown in Fig. 9. The shaping-die and worksupport are then moved downwardly against the spring 37 until the collar 30 has come into contact with the lower guide 17 of the frame C which causes the work-support and shaping-die to stop in the position shown in Fig. 4. During this downward movement the shaping-die and worksupport pass through the externa-l forms and the protruding edge of the blank comes into contact with their inneredges and is turned up by them in the manner shownin Figs. 9 and 10: The lever is then thrown intothe positionshown in Fig. 3 and the `eXternal forms 39, 40 and 48 are simultaneously moved in# wardly toward the shaping-die plate '19. It will be seen from'Fig. 4 that this will cause aV portionof the upwardly extending edge of the blank to Vbe folded sharply over and about the fiange 20 as shown at 82 the remainder of said edge S3 being compressed in an upright position between the edge of the external forms and that ofthe shaping-die plate 19. The collar 30 being locatedsothat. the flange 20 is below the external forms a distance slightly less than the thickness of the material tobe formed, it will be seen that the inward movement of the external forms over the flange will iron the material out over the upper edge of the flange 2O andV draw it tightly into the position `shown in Fig. 4 of the drawings. 'The heavy pressure brought to bear on the material by the lever 55 compresses the material and shapes it as shown, so that when removed from the machine it will retain the form shown in Fig. 6. This construction is importa-nt for I have found that ifuniform pressure is brought to bear simultaneously about all sides of the toe portion of the blank and properly tempered leather is employed that portion of the leather which is required to stretch. slightly and that portion which is required "tobe crowded together will readily do so, whereas if pressure is not applied to all parts simultaneously it is practically impossible to form the lip. The toe form 48is so con-` structed that the portion 520i said form is not quite concentric ywith the corresponding portion of the shaping-dieplate but Va somewhat greater space is left between the two' members about the toes. `The sharp turn made in the lip 83 at this point produces s Awa- 4j Y f 1,152,131:

It is foundthat if the Vproper pressure is applied the article will retain its form without the application;yofY heat, kbut to expedite work the dies will ordinarily be heated. After pressure for sufhcient timehas been brought to bear onthe blank, the lever is thrown back into the position shown in Fig. 1, the shaping-die is raised by the lever 23 and the shaped blank is then removed and replaced by anotherj vawait@ geen frein Fig. 6am aie'biank j thus formed has ga lip 82 and a lip or chan- A right or substantially vertical position and,

therefore, is readily adaptedv to be sewed to the upper and welt of the shoe.

' The. insole member just describedmay be conveniently termed the outer insole member for itis designed to be usedin connection with an A inner insolev memberv shownv in Fig. 8 which iscut and shaped tofit snugly withinthe outer member so that the lipof one lies contiguous with thatof the other.

SInAFig. 7 is shownV my machine provided witha shaping-die 85 adapted to be used in forming the inner member. `The machine parts fare exactly .l the. same as described Y abovewith ,the exception of the shaping-die and work-support,- the form of shaping-die and work-supportshown at 85 and 86 in Fig. 7 being employed. The shaping-die consists; of a 'flat plate similar to the one describedy above with the. exception it has no flange'or bottoinplate vas is necessary when theouter insole member is to be formed and is slightly smaller than the plate 19 of the old shaping-die. The external pressure members 39,40 and 4S maybe properly adjusted for the smaller die and work-support at the v bolt and slot` connections 46. The"collar 30 shouldbe'so adjusted on the rod16 that it'strikes the lower guide V17 when the die and work-support are moved downwardly into the position shown in Fig. 7. The

blank employed is substantially the same as theblank describedheretofore Vwith the 'exception that it isfslightly smaller. i It is pro,-

vided preferably with two incisions 87 in orderfto` permit the outer edge of the Ytoe portiony to be Vformed into the lip 88 shown.

After. properlyradjusting the guides 'Maud 75 the blank is clampedion the work-support inthe same manner -as the outer member and the machine operated as before described. YThe inner insole member isv thus adapted to fit within the outer insole member. The lips 88 and 83 together forming a `thick strong channel nap.

Fig. 11 illustrates the use ofthe machine for the purpose of assembling the insole members. The inner insole member shaping-die and outer'insole member work-support are employed andthel combined members compress between the external forms. Any well known form ,of cement may be employed so that' the members are thus given a final shaping pressure and rmly secured together.

What I claim is: i f

1. The improved insole forming machine comprising a shaping die, side forms and an end form movably mounted about said die and having operating surfacescoperating therewith, separate toggle joint connections for said end form and each of said side forms, and a bell crank lever forming one of said toggles to which each of said other toggles is connected and by which all of said toggles may be simultaneously operated to cause said forms to be simultaneously moved against the shaping die to compress and formthe material.

vvv2. In a machine of the character described thekimproved presser mechanism for forming insoles comprising a shaping-diehaving a pressure surface thel shape of the insole to be formed, a flange of uniform width protruding outwardly about said pressure surface, external presser members movably mounted about said shaping-die and having pressuresurfaces cooperating with the pressure surface of said shaping-die and means for moving said external presser members against the pressure surface of4 said shapingdie and adjacent said ange whereby ablank placed on said shaping-.die is folded sharply upon itself over said fiange and a lip formed between the pressure surfaces of said external forms and the pressure surface of said shaping-die.

3. In a machinev of the character described, thev combination kof asha ing die having a substantially arc shape convex toe portion,.and a toe form having a substantially arc shaped concave portion adapted to coperate therewith, the arc shaped portion of said toe form being of less diameter than the coperating convex surface of said shaping die so that a space is left between the members when in contact.

In testimony whereof I aiiix my signature, in presence of two witnesses.
